Wrote it as a script in a file called RootBrowser.  Changed the
permissions to executable by bill (as usual).  I have bill's PATH
including $HOME/.gnome2/nautilus-scripts.  Tried .RootBrowser from the
command line.  It worked but gave me the last two lines as returns for
the gterm.

Tried it as a single command line. It worked as above.

I did that.

Didn't use sudo -k but it makes sense as a precaution

Knew I probably wanted to background or /dev/null return variabless 1 &
2 above but wasn't sure how to go about it.  Had read some manuals about
file descriptors but have never need to use them, so didn't know how to
use 1 & 2 to send the lines /dev/null.  Tried things that were far too
complex that obviously didn't work.  So, thanks that was the solution I
needed.

Essentially did that.  Knew to do it but hadn't written it yet trying to
keep the number of possible complications down until the rest worked.

Thanks for the explanation.  I'll go back and 'man' for your kind of
comments if I have further questions.
